Multiple 2 Tb partitions RRS feed

  • Question

  • I am new to RAID and WHS, but I have been building PCs for years.  I set up my 'self built' HT server last night and saw the following:

    'Server Storage' reported I had a 4.55 Tb drive (RAID5 Array), unallocated,  and 289.09 Gb 'D' drive (Space left on my boot disk (320 Gb drive))available, which WHS saw as allocated.  When I allocated the 4.55 Tb array I got the below results:

    Total size    - 4.84 Tb (53%)
    Free Space - 2.27 Tb (46%)

    My questions are:
    1) What will WHS do with the free space, if anything?
    2) Should I partition the drive into 3 logical drives (2Tb, 2Tb, left over space)?
    3) How will WHS make use of 3 seperate drives from question 2?
    4) Will this 'break' my 4.55 RAID5 array?

  • Hi,
    Windows Home Server does not support RAID 5, and it does not support GPT disks, which are needed to address more than 2 TB disks. So it is recommended to break the RAID and use the disks as single drives.

    This being said, a potential workaround has been discussed in this thread.
    Such scenarios are not supported and may put your data at increased risk (which you will figure out, if you need to do a server reinstall or other ways of data recovery - also a RAID5 array may fail). Even a WHS or driver update may cause unwanted issues.
    Best greetings from Germany
